STREET-S'WEE'PER.

SPEClFICATION forming part of Letters Patent No. 656,210, dated August21, 1900. Application led December 1.5, 1899. Serial No. 740,449. (Nomodel.)

To all whom it may concern:

Be it known that I, ALPHONSE PIToN, a subject of Her Majesty the Queenof Great Brit! This invention relates to street-sweepers;

and one object is to provide an apparatus of this character which isespecially adapted for removing ice and snow from car-tracks.

A furtherobject is to provide such an ap,- 'paratus with means wherebyit may perform the work of cutting the ice vand snow only, the sweeperbeing adapted to be raised and held in its elevated position.

A further object is to provide an apparatus of this kind which is strongand durable, so as to be able to withstand the rough work for which itis intended.

A further object is to provide such an apparatus with means whereby thesnow and ice or dirt may be automatically'depositedl to one side of thecar-tracks as the work of sweeping progresses.

Finally, the object'is'to provide an apparatus which 'is simple inconstruction, efficient in operation, and economical to manufacture. A

To these ends the invention consists in an apparatus for removing snowand ice from car-tracks,"constructed substantially as hereinafterillustrated and described, and defined in the appended claims.

Referring to the drawings, in which similar letters of referenceindicate similar parts throughout the several views, Figure 1 is a planview of the apparatus in which the invention is embodied. Fig. 2 is aside elevation thereof. Fig. 3 is a vertical central longitudinalsection. Fig. 4 is a plan viewed from below. Fig. 5 is a cross-sectionyon the" line 5 5 of Fig. 2, parts beingshown in `eleva- 5o tion, lookingtoward'the'front'end of the car. In they drawings, A represents the bodyof a car, which may be of any ordinary or pre- ;ferred construction,but, as shown, is an open car operated by electricity. The front end ofthe car'is shown as provided with an ordi- 55 naryv form of motor A.Upon the rear axle and adjacent to each rear wheel is fixed a gear c.and a', which mesh with gears a2 and y :0.3, 'fixed Vupon the shaft co4,while at each end and at the center of said shaft a4 are fixed 6osprocket-wheels a5, a6, and a7. Th'e gears a? and a3 mesh with gears asand a9, fixed upon the shaft am, and the last-named gears mesh withgears a and @12, fixed upon the shaft als. Upon each end of the shaftL13 is fixed 65 a sprocket-wheel@14 and @15, which are con-. nected bysprocket-chains am and @17 to the sprocket-wheels als and al, fixed tothe ends of the shaft d20, which is journaled inthe hood B and carriesthe broom b. The hood 7o B is provided at each end with a supporting`arm b', which are revolubly yconnected at their upper ends to the shaftals. An operating-lever b2 is pivotally mounted in a standard b3, fixedupon the car-platform. To the outer end of the lever b2 is looselysecured a metal bail b4', the lower ends of which engage in perforations4formed in the ends of the hood B. B y this means the hood B, and with4itthebroom b, may be raised up out of con- 8o tact with the` groundwherever it is so desired.l

The hoodB is provided at the lower portion of its inner end with aninclined chute B', which communicates withV that portion of the hoodcarryingthe broom. The inclined chute B is closed at its upper end,*while the lower end is open and extends lto point near l the ground. Byreason ofthe length of. the shaft am and the corresponding width of thehood B the open end or spout of the chute 9o Bextends to a point somedistance Zbey/ond the rails of the tracks, thus permitting the dirt,snow, dto., to be 'deposited away from the rails and leaving a wideclean roadsurface.

Upon each side of the car-body and imlnediately in front of the rearaxle thereof is ixed a depending supportingarm D, in the lower ends ofwhich is journaleda shaft d,

and upon the central portion'ofths shaftis 1c@ fixed a sprocket-wheelCZ, c'onnected'by a sprocket-chain d2 to the sprocket-wheel a on theshaft a4. Upon the shaft d is lixe'd a series of parallel bars cl3,arranged spirally thereon, and between each pair of said bars d3 issecured a series of curved hooks d4, having sharp cutting-points, whichhooks by reason of the spiral arrangement of the bars cl3 are inclinedtoward the outer sides of the car, thus tending in operation to throwthe broken ice, zc., away from the track. Each series of bars and hooksare divided by the sprocketwheel d', and the series on one side of saidwheel are inclined in the opposite direction from those on the otherside of' said sprocketwheel.

Upon each side of the car-body and in front of the shaft d is secured adownwardly-extending support E, having a vertical recess e, withundercut sides, forming a guideway for the adjustable arm E, the lowerend of which is extended laterally, forming a bracket e', in which isjournaled the shaft e2. A sprocket-wheel e3 is centrally fixed upon saidshaft c2, and between said sprocket-wheel and the outer portion of thebracket is secured upon said shaft a series of parallel bars e, arrangedspirally thereon. A series of curved hooks e5, having sharpcuttingpoints, is secured between each pair of said parallel bars, whichhooks, by reason of the spiral arrangement of the said bars, areinclined toward the outer sides of the car, thus tending in operation tothrow the broken ice, die., away from the tracks, being in all respectsconstructed and operating in a manner similar to the hooks d* on theshaft d. A protecting hood or shield E2 is secured to said bracket e'and extends over the hooks c5.

Upon the inner side of the arm E is a' lug e6, which is pivotallyconnected to the end of an operating-lever F, which is pivotallysupported in a suitable standard F', fixed upon the car. Thelever-handle is provided with suitable openings, through which a pin fis inserted and passed through openings in an upright f', whereby thelever is secured in its adjusted position. By means of this constructionit will be evident that the hooks e5 may be lowered into or raised upoutof operative contact with the ice. Sprocket-chains e7 connect thesprocket-wheels e3 with the sprocket-wheels a5 and a7 on the shaft a4.

The foregoing description renders unnecessary a detailed description ofthe operation of the apparatus, it being obvious that the forwardmovement of the rear wheel of the car causes the broom and the severalsets of cutting-hooks to rotate by means of the train of intermeshinggears and the sprocket wheels and chains.

The hooks d4 serve to cut the ice, snow, dac., from between the rails ofthe tracks, While the hooks e5 perform the same work just outside therails. The broom sweeps up the broken ice, dsc., and deposits it intothe inclined chute B', by which it is carried beyond the rail, leaving awide clean space, which extends beyond the outer rail of the tracks.

There are many Yfeatures shown on the drawings which are common to carsof this construction and which need no detailed description of theirconstruction and operation, as they do not pertain to my invention andare shown only that a complete car be shown having the necessaryequipment for carrying out the purpose of a street-cleaning apparatusapplied to a car. Such, for example, is the brake mechanism G, thetrack-sanding device ll, the trolley-beam I, and the device J forsteadying the front axle.

While Ihave herein shown a preferred form of carrying my invention intoeffect, yet I do not desire to limit myself to such preferred details ofconstruction, but claim the right to use any and all modificationsthereof which will serve to carry into effect the objects to be attainedby this invention in so far as such modifications and changes may fallwithin the spirit and scope of my said invention.
